I would love to see the addition of the ability to set up a one-way, or one-direction, tie between books. What I would like to see would be the ability to scroll through a Bible text and have the Commentary scroll along, but then be able to scroll through the commentary without the Bible text moving.

For instance, If I am studying Esther 3:10 and my commentary is more general and is divided by "Esther 1:1-2:20" "Esther 2:20-4:17" "Esther 5:1-6:14" etc... When I scroll to Esther 3:10 the commentary naturally jumps to the section treating "Esther 2:20-4:17." Great. But, now if I scroll the commentary and go to far, my Bible text jumps to Esther 5:1, so I scroll back and my Bible text jumps back to Esther 2:20. Not Good.

I would love to be able to have the Commentary stay in a one-way tie with the text so that it scrolls with my text, but gives me the liberty to scroll through the commentary without changing my Bible Text location.

Ditto that. I just got the Zondervan Bible Backgrounds commentary (that was recently on sale), and what OSchrock describes would make it much more user-friendly, in my view. Not that it's horrible or anything, but a one-way tie would be helpful and keep my study more on track.
